Question 1

How does StealthQL help with AI-written backend code?

Accepted Answer

StealthQL gives Cursor, Claude Code, and Codex a repo-native backend contract. Agents can propose schema, auth, policy, function, and share changes, but the runtime generates attack tests and fails the build before auth leaks, cross-tenant reads, unsafe service-token writes, or over-shares ship.

Question 2

Is StealthQL a database, a backend, or a framework?

Accepted Answer

StealthQL is a backend runtime for the agent era. It compiles your schema, auth, policies, functions, storage, sync, and shares into a capsule that can run locally, on StealthQL Managed, or on your own infrastructure.

Question 3

Can I still use SQL?

Accepted Answer

Yes. StealthQL is built around Postgres-compatible data. You can use the generated client, raw SQL, or both. Policies still apply.

Question 4

Where is my data stored?

Accepted Answer

On your laptop in development (in a private runtime data directory outside the repo). On StealthQL Managed or your own server in production. You can move it anytime via npx stealthql export.

Question 5

Does my data go to GitHub when I push?

Accepted Answer

No. Your code goes to GitHub. Your data stays on whatever machine is running the backend.

Question 6

Can my customers edit data in Excel or Google Sheets?

Accepted Answer

Yes. Any share can have CSV round-trip turned on. The recipient exports to CSV, edits in Excel or Sheets, re-uploads. Schema and policies validate the upload, then changes go into a proposal queue for you to approve — never written directly.

Question 7

Can I bootstrap the backend from an existing spreadsheet?

Accepted Answer

Yes. Drop a CSV or XLSX into the wizard or run npx stealthql import-csv. StealthQL infers tables, columns, types, tenant boundaries, auth roles, shares, and policy tests automatically.

Question 8

What about multi-region or global distribution?

Accepted Answer

Most apps never need it. When you do, point your capsule at Cloudflare and your data lives at the edge automatically. One config flag, no networking expertise, no re-platforming.

Question 9

What about point-in-time recovery?

Accepted Answer

Production capsules are continuously snapshotted. Roll back to any moment in the last 30 days with one command. The append-only event ledger replays to any timestamp deterministically.

Question 10

What if StealthQL goes away?

Accepted Answer

Run npx stealthql export. You get the full source, data, ledger, and rules as a portable bundle. Your app keeps running. The runtime is Apache 2.0 open source forever.

Question 11

What is open source, and what is paid?

Accepted Answer

The stealthql npm runtime is Apache 2.0: install it anywhere, fork it, audit it, redistribute it. StealthQL Studio is proprietary: the hosted dashboard is included with managed plans, and regulated teams can license Self-Hosted Studio to run the same dashboard in their own VPC.
